Live Scribe

See sheet music appear in real-time as you play

Serious

Instant

The Problem

Transcribing music is slow and interrupts creative flow; existing tools aren't real-time

Current Solutions (Not Great)

Notation software (manual entry), audio-to-MIDI tools (slow, inaccurate), write by hand

Who Needs This

Composers, songwriters, music students, musicians who play by ear

Writing down music you're composing or learning by ear is tedious. Live Scribe listens to you play (via mic or MIDI) and displays sheet music notation in real-time. Play a melody, see it appear on the staff. Work out a chord progression, watch it notated. It's instant visual feedback for your musical ideas, and a way to capture compositions without interrupting your creative flow. Export to MusicXML for further editing.

Honest Take

This is genuinely useful for composers. AnthemScore and Soundslice exist but aren't real-time. The MIDI path is straightforward, but audio-to-notation is notoriously hard—even pros struggle with polyphonic transcription. If you nail monophonic input, there's a solid niche for songwriters and students.

Build Prompt

Use this prompt with an AI assistant to start building

Build a React PWA called 'Live Scribe' using WebInfer, Web MIDI API, and Web Audio API. UI: staff display (VexFlow or custom SVG), input selector (MIDI device or mic), settings panel. MIDI mode: Web MIDI API captures notes with timestamps. Accumulate notes in window (e.g., 1 bar based on detected tempo), then render. Audio mode: getUserMedia for mic, run pitch detection (use Pitchfinder library or ML model), convert to MIDI-like events. For both: AI assists with quantization and key detection. Use generateObject with note events to return { keySignature: string, timeSignature: string, notes: [{ pitch: string, duration: string, startBeat: number }], chordSymbols: [{ chord: string, beat: number }], suggestedCorrections?: string[] }. Render to staff in real-time: new measures appear as you play. Quantization slider: strict (snap to grid) vs. loose (preserve timing). Playback button: hear what was transcribed. Export: MusicXML for Finale/Sibelius, MIDI file, PDF of sheet music.
